[Idea] Rearview mirror

This is merely an idea, some may think it is stupid and some may think it is a good idea, but however you put it, this is just an idea and i am not asking someone to take their time to make it.
Although: If you make it please credit me for the idea
Advantages-See enemies trying to sneak up on you and even make chams work for the mirror
Disadvantage-Lose a tiny bit of game window, but for a great cause

its really not that hard of a code to create.
this was one of the ways to make a simple enemy check for behind yourself.
